Level Curve Generator

Generate a table of XP required per level across your whole game, from a base XP and growth rate.

What is the Level Curve Generator?

This tool generates the XP required for the next level and the cumulative XP for every level, from a max level, base XP, and growth rate. It's useful for game developers who want to see how an XP curve grows across a table or chart when designing RPG-style leveling.

How to Use

Enter the max level you want to generate, as a whole number from 2 to 1000.
Enter the base XP required to go from level 1 to level 2.
Enter the growth rate, the multiplier applied at each level.
Press "Generate XP Curve" to see the table, chart, and cumulative XP.
Use the CSV download or table copy as needed.

Example

With a base XP of 100 and a growth rate of 1.2, Lv1→2 needs 100 XP, Lv2→3 needs 120 XP, and Lv3→4 needs 144 XP. The cumulative XP to reach Lv4 is 100 + 120 + 144 = 364 XP.

Using This in Game Development

Before building a level table for a Unity RPG, you can see how required XP grows from the early game to the end game. You can also open the generated CSV in a spreadsheet to help tune quest rewards or enemy XP.

Difference from the XP Calculator

The XP Calculator checks the XP needed from your current level to a target level. The Level Curve Generator produces a full XP table across multiple levels for your entire game.

Notes

The XP required for each level is rounded to a whole number before being added to the running total. Very high growth rates or large input values can exceed a safe numeric range and result in an error. Consider XP bonuses, rewards, and level caps separately for your actual game.

FAQ

Can I generate beyond level 1000?

No. The max level is capped at 1000 to keep the browser load and display manageable.

What does cumulative XP represent?

It's the total XP needed to reach that level. Lv1's cumulative XP is 0, and Lv2's cumulative XP equals the XP required for Lv1→2.

How does a growth rate of 1.2 increase XP?

The base XP is multiplied by the growth rate raised to a power. Lv2→3 is 100 × 1.2 = 120, and Lv3→4 is 100 × 1.2² = 144.
